Referat

Ushbu maqolada grunt o‘zanli kanallarda oqimning urinma kuchlanishini aniqlash va o‘zan tubining yuvilmaslik shartlarini baholash masalasi tadqiq etilgan. Grunt o‘zanli kanallarda oqim ta’sirida yuzaga keladigan urinma kuchlanish o‘zan tubi va yon qiyali klarining deformatsiyasi, yuvilishi hamda kanalning gidravlik barqarorligini belgilovchi asosiy omillardan biri hisoblanadi. Maqolada oqim sarfi, o‘rtacha tezlik, suv chuqurligi, gidravlik qiyalik, gidravlik radius, gruntning granulometrik tarkibi, zichligi va zarrachalar o‘lchamining urinma kuchlanish shakllanishiga ta’siri tahlil qilindi. Amaldagi urinma kuchlanish qiymatlarini kritik urinma kuchlanish bilan taqqoslash asosida grunt o‘zanining yuvilish yoki yuvilmaslik holatini baholash mezonlari ko‘rib chiqildi. Shuningdek, oqimning gidravlik parametrlari va gruntning fizik - mexanik xususiyatlarini hisobga oluvchi yondashuv asosida yuvilmaslik shartlarini aniqlash imkoniyati baholandi. Tadqiqot natijalari grunt o‘zanli kanallarda o‘zan barqarorligini prognozlash, yuvilish xavfini kamaytirish hamda kanalning ishonchli va samarali ishlashini ta’minlash uchun qo‘llanishi mumkin. Taklif etilgan yondashuv sug‘orish va melioratsiya kanallarining gidravlik hisoblarini takomillashtirish hamda o‘zanlarni mustahkamlash zaruriyatini ilmiy asoslashga xizmat qiladi.
